Code:

#include <windows.h>
#pragma comment (lib, "Ws2_32.lib")
#define NETWORK_ERROR -1
#define NETWORK_OK      0

int main() {
WORD sockVersion;
WSADATA wsaData;
int nret;
LPHOSTENT hostEntry;
SOCKET ircsocket;

char buffer[256];
char user[] = "USER blankbot 0 0 blankbot \r\n";

sockVersion = MAKEWORD(1,1);
WSAStartup(sockVersion, &wsaData);

hostEntry = gethostbyname("irc.p2p-network.net");

if(!hostEntry){
   nret = WSAGetLastError();
   printf("Error: %d", nret);
   WSACleanup();
   return NETWORK_ERROR;
}

ircsocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if(ircsocket == INVALID_SOCKET){
   nret = WSAGetLastError();
   printf("Error: %d", nret);
   WSACleanup();
   return NETWORK_ERROR;
}

serverInfo.sin_family = AF_INET;
serverInfo.sin_addr = *((LPIN_ADDR)*hostEntry->h_addr_list);
serverInfo.sin_port = htons(6667);

nret = connect(ircsocket, (LPSOCKADDR)&serverInfo,
            sizeof(struct sockaddr));

if(nret == SOCKET_ERROR){
   nret = WSAGetLastError();
   printf("Error: %d", nret);
   WSACleanup();
   return NETWORK_ERROR;
}
send(ircsocket, user, strlen(user), 0);
printf ("%s\n", user);
Sleep(100);
send(ircsocket, nick, strlen(nick), 0);
printf ("%s\n", nick);
Sleep(100);

char *pch, *j;
while(1){
   memset(buffer, 0, 255);
   recv(ircsocket, buffer, 255, 0);
   printf(buffer);
   printf("\n");

   pch = strstr(buffer, "PING :");
   if (pch) {
      strncpy(pch, "PONG  ", 6);
      send(ircsocket, pch, sizeof(pch), 0);
      printf(pch);
      printf("\n");
   }
   j = strstr (buffer, "End of /MOTD command.");
   if(j){
      send(ircsocket, identify, strlen(identify), 0);
      printf ("%s\n", identify);
      Sleep(100);

      send(ircsocket, join, strlen(join), 0);
      printf ("%s\n", join);

      send(ircsocket, privmsg, strlen(privmsg), 0);
      printf ("%s\n", privmsg);
   }
      

   if ( strlen(buffer) == 0)
      break;
   else {}
}

Sleep(1000);
closesocket(ircsocket);
WSACleanup();
return NETWORK_OK;
}

the issue is with PING and PONG. I receive PING like this
PING :xxxxxxxx
and PONG has to be sent like
PONG xxxxxxxx
So i have to remove the 6th position (a space) in order to continue with the logging in to irc.

Can anyone please help . Sorry if i don't make sense. I've been frustrating over this.


Fixed the PONG by using
for (int i = 5; i < strlen(pch); i++)
pch[i] = pch[i+1];

but now it still doesn't continue.
I receive nothing after the pong, i should be getting server confirmation

Well, in my case, anyway (and this happened a few times), you do get a response from the server: "ERROR :Closing Link: blankbot[ip] <Ping timeout>"

Just wait a while, and throw a getchar() right after the while loop.

I'll play around with it, and see what I can find; I'm assuming you're sending a bad PONG.

Edit:

lol. pch is a pointer, therefore its size is 4. You should replace the

Code:
send(ircsocket, pch, sizeof(pch), 0);


with

Code:
send(ircsocket, pch, strlen(pch), 0);


Edit:

I just tried that, and it seemed to work... Then I got like bombed with all sorts of messages and information. =P

add a Sleep(15000) or higher for 15 seconds or so.. attach WPE PRO to your tool and see what packets you send and recieve exactly byte by byte..

Then compare it with the offical mIRC packets.. that will solve any problem I guarantee it..


P.S.
Code:

for (int i = 5; i < strlen(pch); i++)
pch[i] = pch[i+1];



is same as..

Code:


memcpy((char*)pch,(void*)((DWORD)pch+6), strlen(pch)-5);

the strlen(pch)-5 not sure if it will work.. that loop confuses me.. but what I learned so thats how you handle packets in C++



Also P.S. your problem might be actually the strlen.. if it reaches a byte equal to 0, 00 aka 0x0 aka NULL. It will stop counting.. so your counting system could be flawed then..

a few tests you could do also..
DWORD stuffsent;
DWORD stuffgotback;
stuffsent = send(blah,blah,blah);
stuffgotback = recv(bkah,blah,blah);

just printf the stuffgotback and stuffsent.. to see how much bytes you sent and received this for testing if you send the correct stuff and if you receive the correct amount of bytes.


samuri25404 is right about the send() paramaters you have to send the size of packet not size of pointer which is 4.. so it should still work lol cuz PONG is 4 in size anyways. I'd just hardcore the size with a magic number cuz it will never change anyways..


Almost forgot when you send something to IRC protocol you have to send \r\n at the end of every packet or it will not work

sprintf(pch, "PONG/r/n");

Seemed to work fine for me, without that.

Btw, it's "\r\n" not "/r/n".

Use wireshark, find out what you are actually sending.
